ful Improvements in al Light `Shade, of

' which the following is a specification.

This invention relates to electric lamp shades and has for its primary object the provision, in a manner as hereinafter set forth, of a shade adapted to be secured to the socket carrying the lamp and so constructed as to allow its being freely revolved about the lamp.

The invention broadly comprises a 'collar portion and a light deiiecting element, the collar portion adapted to be clamped about the socketV of an electric lamp and having one end, its forward end, enlarged to receive an annular constiicted portion of the light deflecting element therein, the enlarged collar portion and the consti'icted portion of the light deflecting element being formed to provide a ball bearing connection between the two elements.

Another object of the invention is the provision, iii a manner as liereiaftei' set forth, of a revoluble electric lamp shade of light but durable construction, attract-ive in appearance, and inexpensive to manufacture.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding that the invention is not confined to any strict conformity with the. showing of the drawings, but may be changed and modified .so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings Figure 1 is a vertical longitudinal sectional view of the device embodying this invention, shown as applied to a lamp socket.

Fig. 2 is a vertical longitudinal section of the shade portion.

Fig. 3 is a detail of the collar portion.

Fig. 4 is a section taken on the line 4 4 of Fig. 2, and

Fig. 5 is a section taken on the line 5 5 of Fig. 3.

Referring now to the drawings in detail,

wherein like numerals of reference indicate corresponding parts throughout the several views of the drawing, a lamp socket is indicated at 1 having the usual shoulderat t-lie rear part "1 and carrying a lamp '2, this structure being of the kusual design and formingno part of the present invention.

The structure embodying this invention comprises a Vcollar member 3 having the end' 4 formed of a proper diameter to fit about the socket 1 and having its central portion provided with an outstanding` flange 5 which merges into the enlarged outer end 6 having in its central portion the annular ball race 7 and terminating in the annularI outstanding flange 8. This collar is split throughout its entire length as' indicated clearly at 9 in Fig. 3, and the inner portion 4 is provided upon either side of the division 9 with opposed ear members 10 having threaded apertures therethrough to receive a thumb screw 11 whereby the ear members may be drawn together and the ycollar tightened about the socket of the lamp.

Carried by the collar 3 is a light deflecting element 12 having a constricted portion 13 and terminating in the annular ring 14 which is of substatially the same width as the portion 6, and is provided with the encircling ball race 15 in its outer surface.

As clearly shown in Fig. 1, the ring 14y is adapted to fit within the portion 6 and when in' position, the race 15 is aligned with the race 7 in the portion 6 to receive therein the balls 16.

The ring 14 is of slightly greater diameter than the socket 1, and when placed within the collar and the collar placed upon the socket 1, the screw 11 is tightened, drawing in the inner portion 4 tightly about the.-

socket and causing the outer portion to close suliiciently tight to hold the light deflecting element in proper position, but not clamped too tightly about the lamp to prevent its being turned within the collar.

llVhat I claim is 1. In alamp shade, a split collar adapted to be positioned about a lamp socket, means carried by said collar for tightening the same about the lamp socket, a light defiecting element having means for Iconnection with said clamp, and a ball bearing coupling said cla-mp and'said connecting means.

2. In a lamp shade, a split collar adapted to encircle a lamp socket, opposed outstand-l ing ears positioned one on each side of the said split portion, screw means connecting said ears for drawing said portions together,

a light defleoting element having means for Connection With said Clamp, and a hall bearing coupling said yclamp and said Connecting means.

3. In a lamp shade, a split lamp socket engaging` collar of greater diameter at one end than at the other and having an annular flange at its central part connecting the part of one diameter With that of the other, opposed outstanding ears positioned one on each `side of said split portion, screw means connecting said ears and adapted to dra-W said portions together, a light defleeting element having` means for connection With said clamp, and a ball bearing coupling said clamp and said connecting means.

4. In a lamp shade, a split lamp socket engaging' collar of greater diameter at one end than at the other and having an annular flange at its Central part connecting the part of one diameter With that of the other, opposed outstanding ears positioned one on each side of each split portion, screw means connecting said ears and adapted to draw said portions together, said part of large diameter having a hall race pressed in its inner surface, and a light defleoting element having one end eonstrieted and formed to provide an annular ring having a hall race formed in its outer surface to Cooperate With said first mentioned ball race, said ring; being adapted to revolve Within said part of large diameter upon halls positioned Within said 'Cooperating races.

In testimony whereof, I afliX my signature hereto.

ROBERT GOUDEN.
